Is it permissible for a Muslim working in a funeral home in Germany to transport a Qadiani or Sikh funeral—without washing the body—to their temples and then to the cemetery, knowing that Sikhs cremate their dead, and is this act considered aiding them in their falsehood?

It is permissible to be hired to transport the corpse of a disbeliever to the graveyard, because doing so removes harm from people. However, carrying it to their temples to be burned or to perform one of their rituals is not permissible, because it involves aiding falsehood and condoning it.
